In this article, I will cover how to write out images as Gif images in Java. We also have a related article covering how to read GIF files in Java.
JDeli provides support for GIF along with lots of other image formats.
What is a GIF?
GIF stands for Graphics Interchange Format. It is a lossless, bitmap image format which became popular on the world wide web because it supports transparency and simple animations in browsers. It can support up to 256 different colours from a 24bit range of RGB values. It uses LZW compression (which was subject to patents owned by Unisys). Issues over this in 1990s, led it to be largely replaced by the PNG format in modern usage.
The file name extension for GIF files is: .gif
How to write an image as a GIF file with JDeli
Step 1 Add JDeli to your class or module path. (download the trial jar).
Step 2 Create a File (or OutputStream) object
File file = new File("/path/to/outputFile.gif"));Step 3 Pass image, Heic type, and File (or OutputStream) object into write method
JDeli.write(bufferedImage, "gif", file);In JDeli you can also use a typesafe version
JDeli.write(bufferedImage, OutputFormat.GIF, file);or pass in a object for more control over GIF image output, such as level of Compression.
GifEncoderOptions options = new GifEncoderOptions();
JDeli.write(bufferedImage, options, file); Start reading and writing images with one line of code
Read: BufferedImage image = JDeli.read(streamOrFile);
Write: JDeli.write(myBufferedImage, OutputFormat.HEIC, outputStreamOrFile)
